A NetLogo collision involving 2 sets of cars (Car0 collides with Car2 and Car1 collides with Car3) is set up in order to compare the effects of mass, speed, %elasticity, and time of collision on the impulse and acceleration of the cars. The only difference in the 2 collisions relating to the individual cars is the mass and/or speed of Car0 compared to Car1. You can also set a difference between the top and bottom collisions regarding %elasticity using the  slider. Experiment with the sliders below in order to become familiar with the modeling environment. Click on setup and go to run the model.
